The price of grapes at the grocery store is $1.44 per pound. There are approximately 0.45 kilograms in a pound. To the nearest c

Arlecino [84]

1 lb / 0.45 = 2.22

so approximately 2.22 kilograms per pound

divide price per pound by kilometers per pound

1.44 / 2.22 = 0.648

round to 0.65, so it costs $0.65 per kilogram

Use the relative frequency approach to estimate the probability of the event. In a certain class of students, there are 8 boys f

In-s [12.5K]

Answer:

$P\text{Student will be from Kenilworth}\approx 0.256$

Step-by-step explanation:

We have been given that that there are 8 boys from Wilmette, 5 girls from Kenilworth, 9 girls from Wilmette, 5 boys from Glencoe, 5 boys from Kenilworth and 7 girls from Glenoce.

The total number of students from Kenilworth is 5 boys plus 5 girls that is 10 students.

The total number of students in the class would be $8+5+9+5+5+7=39$

$\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}$

$P\text{Student will be from Kenilworth}=\frac{\text{Number of student from Kenilworth}}{\text{Total number of students}}$

$P\text{Student will be from Kenilworth}=\frac{10}{39}$

$P\text{Student will be from Kenilworth}=0.2564102564$

$P\text{Student will be from Kenilworth}\approx 0.256$

Therefore, the probability, that the student will be from Kenilworth, is approximately 0.256.

Rewrite the equation by completing the square.

Dennis_Churaev [7]

Once you complete the square, the simplified version of this equation is

(2x - 1)^2= 0

If you want to solve for x, subtract 1 and divide by 2.

x = 0.5

A weight lifter does 9.8 J of work while lifting a weight straight upward through a distance of 0.12m. What was the force exerte

gulaghasi [49]

Answer:

The force exerted by the weight lifter is 81.7 N.

Step-by-step explanation:

We can find the force exerted by the weight lifter using the definition of work:

$W = F*d$ (1)

Where:

F: is the force

d: is the displacement

We have W = 9.8 J of work and d = 0.12 m, so by solving equation (1) for F we have:

$F = \frac{W}{d} = \frac{9.8 J}{0.12 m} = 81.7 N$

Therefore, the force exerted by the weight lifter is 81.7 N.

I hope it helps you!
